Computer shutting down

If a new PSU helped I can only imagine that it is underpowered but looking at the spec it should be able to cope.

Have you the latest driver for your card?
And have you checked event viewer? (type event viewer into search box,try the system tab)

And also,32bit will only be able to use 3GB MAX ram,64bit will allow use of 4GB or more :)

Well i have a few events over here... 2 critical Kernel-Power errors ( because computer lost power ), a LOT of errors and even more warnings... Also, i know about the 32bit and 64bit "thingy", but at the computer service ( that's how you call that place where "professionals" repair your computer, right? ) they installed the 32bit version and i am to lazy to change it to 64bit...

Also, i have the latest video card drivers. Thanks for the respond!

Will changing my power plan to high performance help? I tried power saver and balanced and it didn't help... But i doubt high performance would help because then my computer would just use more power.

EDIT: Will, maybe, reinstalling Windows or maybe even removing 1 2GB RAM module help?

FWIW: I have found PC's shutting down due to heat problems, One is that the cpu cooler gets a fine mesh of dust from carpets, cats, dogs and other type hair on it. This reduces the cooling of the cpu fan and it could just shut off your system. Also, if your cpu was not installed properly, ie.. conductive grease on top to the heat sink, this could allow your cpu to overheat. Same with your video card if it has a fan on it.

Things to check.

I removed 1 RAM module ( 2GB DDR2 ) and downloaded Everest. I didn't check the temperatures... I don't know how... However, i noticed a strange detail, my cpu uses 1 core ( checked while not playing games ). Is this weird, or is it how it should be?

Go to msconfig(Start>Run), then open the 'Boot' tab, go to the 'Advanced Options' and uncheck 'Number processors'
